Answer:

(3, - 4 )

Step-by-step explanation:

Given the 2 equations

5x + 2y = 7 → (1)

4x + y = 8 → (2)

Rearrange (2) expressing y in terms of x by subtracting 4x from both sides

y = 8 - 4x → (3)

Substitute y = 8 - 4x into (1)

5x + 2(8 - 4x) = 7 ← distribute and simplify left side

5x + 16 - 8x = 7

16 - 3x = 7 ( subtract 16 from both sides )

- 3x = - 9 ( divide both sides by - 3 )

x = 3

Substitute x = 3 into (3) for corresponding value of y

y = 8 - 4(3) = 8 - 12 = - 4

solution is (3, - 4 )

0,0

3,9

-2,-6

4,12

Step-by-step explanation:

distribute

3(2x+1)=15

6x+3 = 15

subtract 3 from both sides

6x + 3 = 15

6x + 3 - 3 = 15 - 3

simplify

6x= 12

divide both sides by 6

answer= x=2

Step-by-step explanation:

Answer:

x= 114°

Step-by-step explanation:

It has four sides so it should add up to 360°

So add> 101+100+45= 246

Then subtract> 360- 246= 114°

Answer:

The correct answer is 1 for the first part, and 12n+8 for the second part.

Step-by-step explanation: I got them wrong for you guys. Edge 2021.

The product of the expression given is 12n + 8.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

The given expression is ([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4)

Multiplying the numerators together,

([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8 (9n² - 4)] / [6n - 4]

                         = {8 [ (3n)² - (2)² ] } / {6n - 4}

We have an algebraic identity, a² - b² = (a + b) (a - b)          

Using this identity (3n)² - (2)² = (3n + 2) (3n - 2)

And the expression in the denominator, 6n - 4 = 2 (3n - 2)

([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8 (3n + 2) (3n - 2)] / [2 (3n - 2)]

The expression 3n - 2 gets cancelled as it lies in both numerator and denominator.

([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8(3n + 2)] / [2]

                         = 4 (3n + 2)      

                         = 12n + 8

Hence the product is 12n + 8.

Answer:

x = ∛(-21/6)

Step-by-step explanation:

Multiply both sides by 20 to remove the fractional coefficients:

5x^3 = -108

Divide both sides by 5:  

x^3 = -21/6

Then x = ∛(-21/6)

Answer:

y - 3 = -1/2(x-1)

Step-by-step explanation:

Given the coordinates (1, 3) and (5,1). The point slope form is expressed as;

y - y0 = m(x-x0)

m is the slope

(x0, y0) is the required point

Get the slope

m = 1-3/5-1

m = -2/4

m = -1/2

Using the point (1,3), substitute

y - 3 = -1/2(x-1)

2(y-3) = -(x-1)

Hence the required equation is y - 3 = -1/2(x-1)

Answer:

y - 3 = -1/2(x-1)

Answer:

I'm pretty sure its a, if not b

Answer:

Step-by-step explanation:

Brian could have more juice than Sonya in actual sense, This is because the representation used, that is the container has been calibrated to show tenth. This means that decimal values of juice in the container will not show explicit volume beyond tenth. Hence the volume will be rounded.

For instance, if the actual volume of juice Brian has Is 0.74 and that owned by Sonya is 0.69. In actual sense, 0.74 > 0.69 . However, if both pour their juice into the calibrated container, Brian's volume will be rounded to the nearest tenth as 0.7 and Sonya's (0.69) will also be rounded to 0.7.

But in actual sense, Brian has more Juice than Sonya.
